Host classic ASP in an ASP.NET Core 8 project

I have a situation where I need to migrate a very old classic ASP website gradually into an ASP.NET Core 8 website.

In my research I found many people asking how but never found a fully working example, so I want to share this for others.

If you end up using any of this, my only ask is that you link to this gist and give me some credit in your code for the next developer to discover... and of course tell me about how it saved your life in the gist comments ☺

Solution Summary:

• add ISAPI handler in web.config for each file extension to process as classicASP
• put classicASP files in wwwroot folder of your aspNetCore project

How to synchronize classicASP session with ASP.NET Core 8

This is related to my other gist where I use both ASP.NET Core 8 and classic ASP in the same website. You'll probably want to read that too if you're needing to do what I describe in this gist.

My original version of this was for MVC 5 several years ago. I have a separate gist of the MVC 5 version here. It worked so well I decided to refactor it for a new project I'm working on.

The code in this gist is fresh out of the oven. Everything I set out to do is working well, but not in production yet so there could be some edge cases I missed. Let me know if you run into something.

I dramatically changed the C# side of it for this new version because the coding strategy differs so dramatically between MVC 5 and ASP.NET Core 8. The classicASP side of it is mostly the same as the prior version asi

npm install -D acorn babel-loader @babel/core @babel/preset-env babel-polyfill webpack webpack-cli uglifyjs-webpack-plugin --save-dev

webpack-cli and acorn are dependencies that you, unfortunately, have to install if you want to run this god damn thing without any obscure warnings or errors.
